feat: Add gh skill support for one-line skill installation via GitHub CLI

[sanoakr]

Summary

This is a feature request to support gh skill — the GitHub CLI extension for Claude Code skill management — so that users can install skills from this repository with a single command.

Motivation

Currently, installing skills from this repository requires manual steps:

1. Clone or browse the repository
2. Locate the relevant SKILL.md file
3. Copy it into the local ~/.claude/skills/ directory

The Claude Code CLI offers a gh skill mechanism that allows skill discovery and installation directly from GitHub-hosted skill repositories, similar to how gh extension install works for GitHub CLI extensions. Supporting this would make the 140+ scientific skills in this repo immediately accessible to any Claude Code user with a single command.

Proposed Experience

# Install a specific skill directly from this repo
gh skill install K-Dense-AI/scientific-agent-skills/bioinformatics

# Browse available skills
gh skill list K-Dense-AI/scientific-agent-skills

What Would Be Needed

• Verify or add the skill metadata/index structure expected by gh skill (e.g., a top-level skills.json manifest or conforming directory layout)
• Update the README with a gh skill installation section
• Optionally, add a CI step to validate the index stays in sync with new skill additions

Why This Matters

• Lower friction: researchers can go from "I heard about this repo" to "skill is running" in one command
• Discoverability: gh skill search surfaces skills without requiring users to know the repo URL
• Consistency: aligns with the broader Claude Code ecosystem tooling

Happy to discuss the required format or open a follow-up PR once the direction is confirmed.

$ gh skill install K-Dense-AI/scientific-agent-skills
Using ref v2.38.0 (75c41d78)
no skills found in K-Dense-AI/scientific-agent-skills
  Expected skills in skills/*/SKILL.md, skills/{scope}/*/SKILL.md,
  {prefix}/skills/*/SKILL.md, {prefix}/skills/{scope}/*/SKILL.md,
  */SKILL.md, or plugins/*/skills/*/SKILL.md
  This repository may be a curated list rather than a skills publisher

doesn't work fyi
